How blockchain can back PoPI

Published

on

Blockchain is built for protecting information, one of its major selling points. But VISHAL BARAPATRE – Chief Technical Officer at In2IT Technologies, asks what effect the PoPI act have on it.

The Protection of Personal Information (PoPI) Act is looming on our horizon. South African organisations are busily preparing for it despite there still being much debate about what the real impact will be and whether or not it will be truly effective. However, one thing is certain, a legislation that protects personal information (that is, any information relating to an identifiable, living person) is necessary, and any technology which could support PoPI within the business should be seriously considered.

One technology that seems purposefully built for protecting information is the blockchain. Although one of the selling points of blockchain technology is its inherent transparency, it certainly has effective security measures. This begs the question, could the transparency of blockchain technology conflict with the regulations that PoPI lays out, or does it add another mechanism for compliancy?

The blockchain, and PoPI compliancy

With the implementation of PoPI, organisations will need to be more sensitive around the privacy of their customers’ information – or be penalised. To do so, they will have to be more organised around the storage, use and dissemination of this data so as not to overstep the bounds of PoPI, and to take care of their customers’ privacy. There needs to be a level of ‘proof’ of where the data is kept, how it is used and who has access to it at any given time. This requirement fits in with the purpose of the blockchain: to provide a verifiable record of any data transaction, including who accesses the said data.

The blockchain is a shared digital transactional ledger that securely records and regularly reconciles transactions of virtually anything of value. Therefore, Blockchain provides accurate traceability and in turn, promotes accountability. Essentially, what the blockchain does for data storage is provide ratified certainty that all the due diligences have been conducted around a piece of data, and a means for recourse should data be unlawfully used or accessed.

There is also the security factor, which appeals to compliancy requirements of PoPI. The blockchain offers unparalleled security features, given its multi-verification nature and tamper proof mechanism of protecting already verified data. If current trends are anything to go by, the blockchain will only get more secure, which makes it ideal for use as a potentially impenetrable storage mechanism.

Any concerns?

The question around transparency still exists. Surely a platform that specifically highlights transparency as a benefit automatically precludes it from being suitable for an act which stresses the protection of a person’s privacy? Not necessarily…

A blockchain can be programmed with certain pre-defined rules, or permissible actions, around what may be done with any piece of personal information, based on the type of information it is. Although the information may be visible to anyone with access to the blockchain on which it sits, these parameters automatically create alerts when certain data is accessed, used, or disseminated in any way that falls outside their bounds.

Granted, there is still the risk that the data may be accessed by unauthorised individuals, but the organisation will be alerted and can take immediate action. The blockchain provides verifiable proof of who accessed the data illegally, for what reason, and what was done with the data. It can then be raised with the PoPI regulator, if required, or can take internal action, as desired (or as required by policy and/or law).

The only real grey area with using the blockchain for complying with data storage, is that there will exist a permanent, in-erasable record of the data, indefinitely. PoPI does define that an organisation must honour an individual’s request for their data to be removed once it is no longer in use. The immutability of the blockchain could prove a problem, nevertheless an organisation still retains control of who may or may not access the data, and could exercise that control to ensure that the data remains all but invisible for its lifespan.

Legion gets a pro makeover

Lenovo’s latest Legion gaming laptop, the Y530, pulls out all the stops to deliver a sleek looking computer at a lower price point, writes BRYAN TURNER

Published

Gaming laptops have become synonymous with thick bodies, loud fans, and rainbow lights. Lenovo’s latest gaming laptop is here to change that.

The unit we reviewed housed an Intel Core i7-8750H, with an Nvidia GeForce GTX 1060 GPU. It featured dual storage, one bay fitted with a Samsung 256GB NVMe SSD and the other with a 1TB HDD.

The latest addition to the Legion lineup has become far more professional-looking, compared to the previous generation Y520. This trend is becoming more prevalent in the gaming laptop market and appeals to those who want to use a single device for work and play. Instead of sporting flashy colours, Lenovo has opted for an all-black computer body and a monochromatic, white light scheme. 

The laptop features an all-metal body with sharp edges and comes in at just under 24mm thick. Lenovo opted to make the Y530’s screen lid a little shorter than the bottom half of the laptop, which allowed for more goodies to be packed in the unit while still keeping it thin. The lid of the laptop features Legion branding that’s subtly engraved in the metal and aligned to the side. It also features a white light in the O of Legion that glows when the computer is in use.

The extra bit of the laptop body facilitates better cooling. Lenovo has upgraded its Legion fan system from the previous generation. For passive cooling, a type of cooling that relies on the body’s build instead of the fans, it handles regular office use without starting up the fans. A gaming laptop with good passive cooling is rare to find and Lenovo has shown that it can be achieved with a good build.

The internal fans start when gaming, as one would expect. They are about as loud as other gaming laptops, but this won’t be a problem for gamers who use headsets.

Serious about security? Time to talk ISO 20000

Published

on

By EDWARD CARBUTT, executive director at Marval Africa

The looming Protection of Personal Information (PoPI) Act in South Africa and the introduction of the General Data Protection Regulation (GDPR) in the European Union (EU) have brought information security to the fore for many organisations. This in addition to the ISO 27001 standard that needs to be adhered to in order to assist the protection of information has caused organisations to scramble and ensure their information security measures are in line with regulatory requirements.

However, few businesses know or realise that if they are already ISO 20000 certified and follow Information Technology Infrastructure Library’s (ITIL) best practices they are effectively positioning themselves with other regulatory standards such as ISO 27001. In doing so, organisations are able to decrease the effort and time taken to adhere to the policies of this security standard.

ISO 20000, ITSM and ITIL – Where does ISO 27001 fit in?

ISO 20000 is the international standard for IT service management (ITSM) and reflects a business’s ability to adhere to best practice guidelines contained within the ITIL frameworks. 

ISO 20000 is process-based, it tackles many of the same topics as ISO 27001, such as incident management, problem management, change control and risk management. It’s therefore clear that if security forms part of ITSM’s outcomes, it should already be taken care of… So, why aren’t more businesses looking towards ISO 20000 to assist them in becoming ISO 27001 compliant?

The link to information security compliance

Information security management is a process that runs across the ITIL service life cycle interacting with all other processes in the framework. It is one of the key aspects of the ‘warranty of the service’, managed within the Service Level Agreement (SLA). The focus is ensuring that the quality of services produces the desired business value.

So, how are these standards different?

Even though ISO 20000 and ISO 27001 have many similarities and elements in common, there are still many differences. Organisations should take cognisance that ISO 20000 considers risk as one of the building elements of ITSM, but the standard is still service-based. Conversely, ISO 27001 is completely risk management-based and has risk management at its foundation whereas ISO 20000 encompasses much more

Why ISO 20000?

Organisations should ask themselves how they will derive value from ISO 20000. In Short, the ISO 20000 certification gives ITIL ‘teeth’. ITIL is not prescriptive, it is difficult to maintain momentum without adequate governance controls, however – ISO 20000 is.  ITIL does not insist on continual service improvement – ISO 20000 does. In addition, ITIL does not insist on evidence to prove quality and progress – ISO 20000 does.  ITIL is not being demanded by business – governance controls, auditability & agility are. This certification verifies an organisation’s ability to deliver ITSM within ITIL standards.

Ensuring ISO 20000 compliance provides peace of mind and shortens the journey to achieving other certifications, such as ISO 27001 compliance.
